I understand you've created the dependency link in Aha! with Jira, it would be great to have this in ADO (Azure DevOps) too please
Dependency syncing is here for the Aha! Roadmaps and Azure DevOps integration. You can now map record links in Aha! with work item links in Azure DevOps — so everyone can instantly see the work that impacts their plans.
If you already have an integration with Azure DevOps, go to the Mappings step, click "Reload configuration", then add a field mapping for Aha! record links <-> Azure DevOps related work.
